1. An enzyme has a Km of 4.7x10-5 M. If the Vmax of the preparation is 22 µmoles. Litre -1.min.-1. What velocity would be observed in the presence of 2x10 -4 M substrate and 5x10 -4 M of a) Competitive inhibitor b) a non-competitive inhibitor c) an uncompetitive inhibitor. KI in all three cases is 3x10 -4 M. d). What is the degree of inhibition in all three cases?​

Sulfur dioxide and oxygen react to form sulfur trioxide during one of the key steps in sulfuric acid synthesis. an industrial chemist studying this reaction fills a 25.0l tank with 4.5 mol of sulfur dioxide gas and 4.5 mol of oxygen gas at 30.°c. he then raises the temperature, and when the mixture has come to equilibrium measures the amount of sulfur trioxide gas to be 1.4 mol. calculate the concentration equilibrium constant for the reaction of sulfur dioxide and oxygen at the final temperature of the mixture. round your answer to 2 significant digits.
